Deutsch Autosport ASU (Ultra-Miniature) Series — 3-Way Flange Pin (Male)
The Deutsch Autosport ASU 3-Way Flange Pin (Male) — Red Key (N) — SKU: ASU003-03PN-HE is a genuine MIL-spec-grade panel-mounted connector for 3-circuit sensor, actuator, and switch sub-harness separable joins in professional race cars, rally, hillclimb, and high-performance builds across Norway, Sweden, and Denmark. This is the pin half of the mated pair — Socket (Female) must be ordered separately to complete the join.
Shell and Circuit Count — ASU003, 3-Way
The ASU series is the smallest-format circular connector in the Deutsch Autosport family, designed for ultra-compact sensor sub-assemblies, low-channel signal interfaces, and weight-critical race car loom builds where the standard AS or ASX body is too large. The ASU003 is the ASU003 — ultra-miniature flange-mount shell for panel and bulkhead installations. At 3 circuits, this connector is suited to 3-circuit sensor, actuator, and switch sub-harness separable joins. Common applications include 3-wire sensor assemblies (MAP, TPS, CLT, IAT), individual coil-on-plug sub-connectors, 3-wire actuator feeds, and small auxiliary circuit groupings.
Red Key (N) — Mis-Mate Protection
Red N is the non-keyed (neutral) variant — it mates with any counterpart of the same circuit count and shell size, regardless of key colour. This makes it the correct choice for service tools, test jumpers, PDI connectors, and any interface where mating flexibility is preferred over strict mis-mate protection. Red N does not enforce a directional pairing between two specific connector halves. It is used by race teams and wiring specialists across Norway, Sweden, and Denmark wherever flexible connection points are required.
Flange Mount — Panel and Bulkhead Installation
The flange connector mounts through a panel cutout via its integral aluminium flange — fixing one half permanently to the chassis, firewall, or bulkhead. The mating cable-mounted half plugs directly into the fixed half, creating a precise, repeatable separable interface at the panel itself. This is the standard for primary chassis separation points, engine bay to cabin firewall joins, and fixed bulkhead interfaces. Flange connectors are the professional choice for motorsport workshops across Norway, Sweden, and Denmark.
